我正在尝试并行运行两种测试方法。启动测试后，URL 仅在一个浏览器上启动，并在第二次测试时变为空白。我还观察到，如果我删除驱动程序管理（）窗口（）最大化（）；删除 Cookies 等，然后为两个测试启动 URL，尽管一个测试被执行，另一个测试失败，并出现错误'stale element reference: element is not attach to the page document'。

谁能告诉我我们如何实现并行测试？

    public class CheckDepartmentsTest extends TestBase{


        public CheckDepartmentsTest() {
            super();

        }
        @BeforeMethod()
        public void setup() throws IOException {
            initialization(URL,pageLoadTimeout,implicitlyWait,ExplicitWait,Path_Current_Direc);
            Loginlogout=new LoginLogout(driver);

        }

        @Test(/*priority=3,*/enabled=true)
        public void Login_LogoutTest() throws IOException {
            Loginlogout.LoginLogoutTest(driver,action,wait);

        }

        @Test(/*priority=2,*/enabled=true)
        public void Search_Product_CheckoutTest() throws InterruptedException, IOException {


            Checkdepartments=Loginlogout.Go_To_Departments(driver,action);
            Checkdepartments.Select_Electronics_Headphones(driver,wait);
            Checkdepartments.Select_MacBook_From_SearchBox(driver,wait);

        }

        @AfterSuite()
        public void teardown() {
            driver.quit();
        }
    }

您需要使用 ThreadLocal 使 WebDriver 线程安全。当您并行运行该方法时，它会为 TestBase 中定义的 Webdriver 创建问题。请检查下面的代码。您应该将线程本地实现移动到单独的类中。现在以修改您的代码为例。

public class CheckDepartmentsTest extends TestBase{


    public CheckDepartmentsTest() {
        super();

    }
    @BeforeMethod()
    public void setup() throws IOException {
        initialization(URL,pageLoadTimeout,implicitlyWait,ExplicitWait,Path_Current_Direc);
        Loginlogout=new LoginLogout(TestBase.driveSafe.get());

    }

    @Test(/*priority=3,*/enabled=true)
    public void Login_LogoutTest() throws IOException {
        Loginlogout.LoginLogoutTest(TestBase.driveSafe.get(),action,wait);

    }

    @Test(/*priority=2,*/enabled=true)
    public void Search_Product_CheckoutTest() throws InterruptedException, IOException {


        Checkdepartments=Loginlogout.Go_To_Departments(TestBase.driveSafe.get(),action);
        Checkdepartments.Select_Electronics_Headphones(TestBase.driveSafe.get(),wait);
        Checkdepartments.Select_MacBook_From_SearchBox(TestBase.driveSafe.get(),wait);

    }

    @AfterSuite()
    public void teardown() {
        TestBase.driveSafe.get().quit();
    }
}

Base Class:-

public class TestBase {

   // public  WebDriver driver;
    protected static InheritableThreadLocal<WebDriver> driveSafe = new InheritableThreadLocal<WebDriver>();
    public  Properties prop;
  //  public  WebDriverWait wait;
    public  Actions action;
    public String URL;
    public String path;
    public String Path_Current_Direc;
    public String currentDir = "\\QATest\\src\\main\\java\\com\\amazon\\Screenshot";
    public LoginLogout Loginlogout;
    public CheckDepartments Checkdepartments;
    public  long pageLoadTimeout;
    public  long implicitlyWait;
    public  long ExplicitWait;


    public TestBase() {
        try {
            prop= new Properties();
            FileInputStream file=new FileInputStream(TestUtil.Config_File);
            prop.load(file);
            URL=prop.getProperty("URL");
            Path_Current_Direc=System.getProperty("user.dir");
            pageLoadTimeout=15;
            implicitlyWait=10;
            ExplicitWait=8;


        } catch (Exception e) {
            e.printStackTrace();
        }

    }

public  void initialization(String URL,long pageLoadTimeout,long implicitlyWait ,long ExplicitWait,String path_Current_Direc) throws IOException {

            if(prop.getProperty("Browser").equalsIgnoreCase("firefox")) {
                System.setProperty("webdriver.gecko.driver",Path_Current_Direc+"\\src\\main\\java\\com\\amazon\\utility\\geckoTestBase.driveSafe.get().exe");
                TestBase.driveSafe.set(new FirefoxDriver());
            }
            else {
                System.setProperty("webdriver.chrome.driver",Path_Current_Direc+"\\src\\main\\java\\com\\amazon\\utility\\chromeTestBase.driveSafe.get().exe");
                TestBase.driveSafe.set(ChromeDriver());
            }
            action=new Actions(driver);
          //  wait=new WebDriverWait(driver, ExplicitWait);
            TestBase.driveSafe.get().get(URL);
            TestBase.driveSafe.get().manage().window().maximize();
            TestBase.driveSafe.get().manage().timeouts().pageLoadTimeout(pageLoadTimeout, TimeUnit.SECONDS);
            TestBase.driveSafe.get().manage().timeouts().implicitlyWait(implicitlyWait, TimeUnit.SECONDS);
System.out.println("Thread Check  "+ Thread.currentThread().getName());
    }
}
